Answer:

4.5 or 4 and a half

Step-by-step explanation:

9/10 divided by 2/10

put 2/10 into it's reciprocal and multiply it by 9/10

10/2 * 9/10

10      9

_     *  _

2        10

^ (visualization)

multiple into 90/20, divide numerator and denominator by 10 to get 9/2

9/2 is 4.5

If a line crosses the y-axis at (0,1) and has a slope of 4/5, what is the equation of the line ?
stepladder [879]
The slope intercept form of a line is y=mx+b, where m is the slope and b is the y-intercept (the value of y when x=0).  We are given that the slope is 4/5 and the point (0,1) so we know m=4/5 and b=1 so:

y=4x/5+1  now to rearrange into standard form ax+by=c

y=(4x+5)/5

5y=4x+5

5y-4x=5

So the answer is D.

However, by convention, in standard form, the equation is usually expressed with a positive coefficient for x.

5y-4x=5 SHOULD be expresses so the x has a positive coefficient, divide both sides by -1 and you have the technically correct form:

4x-5y=-5

Apparently whomever/whatever posed this question to you was unaware of this convention :P

The inequality 10.45b + 56.50 < 292.67 is used to find the number of boxes (b) that can be loaded on a truck without exceedin
PSYCHO15rus [73]
We solve the inequality by subtracting 56.50 from both sides of the equation,
                                10.45b + 56.50 - 56.50 < 292.67 - 56.50 
                                        10.45b < 236.17
Then, divide both sides of the inequality by 10.45
                                             b < 22.6
The solution suggests that the number of boxes than can be loaded on a truck without exceeding the weight limit of the truck should always be lesser than 22.6. Since we are talking about number of boxes, the maximum number of boxes that can be loaded should only be 22.
